Portland police officers found Caleb Grotberg, 32, early Monday morning walking outside near the couple’s home in the 3200 block of Southeast 22nd Avenue with blood on his face and shirt. Grotberg’s 22-year-old girlfriend called 911 about 2:30 a.m.

They found the woman bloody and barely able stand inside a room that Grotberg had barricaded shut with furniture, according to a probable cause affidavit filed in Multnomah County Circuit Court.

The woman told investigators she was upset with Grotberg after discovering he had ingested cocaine, the affidavit said.

After going out to dinner, Grotberg confronted his girlfriend, grabbed and shoved her through a bedroom door, the affidavit said. She was thrown so hard she damaged the door and a dresser about 10 feet across the room when she landed head-first against it, the affidavit said.

As the woman struggled to stand, Grotberg wrapped his hair around her neck, shoved her down, choked her and banged her head on the floor, the affidavit said.

Grotberg continued to punch, choke, and throw the woman, the affidavit said. He began suffocating her by pinching her nose at one point, and told her he was going to kill her, the affidavit said.

"You won't see the light of day," Grotberg allegedly told her.

The woman told investigators she thought she was going to die.

Grotberg threw her into a room, blocked the door and left the house, the affidavit said. She was able to call police from inside the room.

Grotberg was arraigned in Multnomah County Circuit Court on Tuesday on a series of domestic violence-related charges including kidnapping, attempted assault, assault, menacing and strangulation.

He did not enter a plea and is due back in court on Jan. 16.

Police say people should call 9-1-1 immediately to report domestic violence. The Portland Women’s Crisis Line provides 24-hour support and resources at 503-235-5333 or 1-888-235-5333.
